The invention relates to the technical field of stratospheric airships, and discloses a propeller linkage driving device shafting and a stratospheric airship. The shafting comprises an outer rotor, an inner stator, a first bearing, a second bearing, an outer rotor shaft, an outer rotor shaft supporting frame, an inner stator shaft and an inner stator shaft supporting frame, one end of the outer rotor shaft is fixedly connected with a propeller, and the other end is fixedly connected with the outer rotor; one end of the inner stator shaft is fixedly connected with the inner stator, and the other end of the inner stator shaft is fixedly connected with the inner stator shaft supporting frame; the first bearing and the second bearing are both arranged on the outer rotor shaft, and a preset distance is reserved between the first bearing and the second bearing; inner rings of the first bearing and the second bearing are fixedly connected with the outer rotor shaft, and outer rings of the first bearing and the second bearing are fixedly connected with the outer rotor shaft supporting frame; and the outer rotor shaft supporting frame is fixedly connected with the inner stator shaft supporting frame. The span between the two stress bearings is increased, torsion borne by the first bearing is reduced, and therefore the service life of the bearings is prolonged.

    本发明涉及平流层飞艇技术领域,公开一种螺旋桨链接驱动装置轴系和平流层飞艇。包括:外转子、内定子、第一轴承、第二轴承、外转子轴、外转子轴支撑架、内定子轴和内定子轴支撑架;外转子轴的一端与螺旋桨固定连接,另一端与外转子固定连接;外转子包围内定子,内定子轴的一端与内定子固定连接,另一端与内定子轴支撑架固定连接;第一轴承和第二轴承均设置在外转子轴上,第一轴承和第二轴承相距预定距离;第一轴承和第二轴承的内圈均与外转子轴固定连接,外圈均与外转子轴支撑架固定连接;外转子轴支撑架和内定子轴支撑架固定连接。本发明采用增大两个受力轴承之间的跨距,减小第一轴承承受的扭力,从而延长轴承的使用寿命。
